The Transalpine Pipeline ( TAL , even Transalpine Pipeline ) is an oil - pipeline from the port of Trieste in the Bay of Muggia over Ingolstadt to Karlsruhe and a central four oil supply lines in Germany.

The pipeline runs over a total of 465 kilometers with a diameter of 40 inches (1.016 meters) from Trieste to Lenting near Ingolstadt and subsequently with a diameter of 26 inches (66 centimeters) over 21 kilometers to Neustadt an der Donau and over 266 kilometers to it Karlsruhe. It crosses the Alps in this way and comes to Austria on the Italian-Austrian border near Kötschach-Mauthen in Carinthia . The Adria-Vienna pipeline to Schwechat branches off here near Würmlach . The pipeline reaches Germany on the Austrian-Bavarian border near Kufstein .

The construction

In 1963, the US company Bechtel determined the feasibility of an oil pipeline across the Alps within four months. It then took a year and a half to obtain the rights of way from more than 6000 owners. After three years of construction, the line was put into operation in 1967. The total cost was $ 192 million. The average coverage of the pipeline is one meter, it reaches a geographic height of up to 1500  m and crosses the main Alpine ridge under the Felbertauern in a 7.3 kilometer long tunnel . In addition, it leads further south through the 6.9 kilometers long Plöcken tunnel and north of the Felbertauern through the Hahnenkamm tunnel (6.8 kilometers) near Kitzbühel .

The welded steel pipes were coated with bitumen (jute) mats to prevent corrosion . To protect these mats from softening due to solar radiation during storage or transport, they were coated with white lime . The white covering not only acts as a radiation shield, but also as a separating agent to prevent pipes lying on top of one another from sticking together or with lifting accessories and has a corrosion-reducing effect, as the basic calcium oxide neutralizes humic acids .

Infrastructure

The pipeline is monitored by three control centers in Trieste, Kienburg near Matrei in East Tyrol and in Lenting. The Italian control center is operated by the “Società Italiana per l'Oleodotto Transalpino SpA”, while the branch in Austria is the “Transalpine Ölleitung in Österreich Ges.mbH”. In Germany, the "Deutsche Transalpine Oelleitung GmbH" is responsible for the operation.

Ten pumping stations between Trieste and Karlsruhe transport the oil. Tank farms for the intermediate storage of crude oil are available in Lenting (capacity 318,000 cubic meters) and San Dorligo della Valle (capacity 2,000,000 cubic meters).

Pipeline power plant

The world's first oil pipeline power plant has been in operation since autumn 2018. It works in the same way as a drinking water power plant , but with the medium crude oil. On the downhill section of the Felbertauern-Mittersill valley, the pressure build-up due to the topology of the Alpine pass is used to recover 11.5 GWh of electrical energy annually, 12% of the pumping effort of the valley in Austria. The system was built in a tight tub and largely poured in to protect against natural hazards. The construction took three years and cost 11 million euros.

Connection

Branches from other operators lead to Schwechat ( the OMV AWP branches off at Würmlach in Carinthia ), Burghausen (branch of the 12 "OMV line at the Steinhöring pumping station), Vohburg an der Donau and Litvínov .

Since the closure of the Central European Line (CEL) in 1997, TAL has supplied all of the crude oil for the oil refineries in Bavaria and the Bavarian chemical triangle .

Transport performance

Between the start of operations (1967) and 2019, 1.5 billion tons of crude oil were transported. In 2018, 41.6 million tons were transported.
